Continuation of application Serial No.

This invention relates to machines for laying soles and herein illustrated as embodied in a machine for laying upon the bottom of a shoe an unvulcanized rubber sole" which is later to bevulcanized.

In laying a rubber sole it is usually desirable, not only to press the sole firmly against the bottom of the shoe, but also to press its margin more or less against the lowerportions ofvthe sides of the shoe. In some rubber soled footwear, such as sneak ers, the upward bending of the edge or margin of'the sole is comparatively slight; but in other types of rubbersoled footwear, such as rubber boots and arctics, the margin of the sole is sometimes rolled up around the sides of thebootor shoe for half an inch or more. i

In order to provide means for laying various types of soles, one feature of the invention comprises a novel elastic member.

extending across an opening so that when a lasted shoe with a' sole attached is forced against the elastic member and into the opening, pressure will be exerted both directly against the bottom of the shoe and in a direction to bend up the margin of the sole and press it against the sides of the shoe. In the illustrative machine a series of round rubber cords are stretched across an opening in a frame, the ends of the cords being anchored to the frame so that the cords function independently; and, in order to insure a more uniform pressure upon the sole, one or more rubber blankets are laid on top of the series of cords so as to envelop the lower portion of the shoe when the shoe is forced into the opening. Unvulcanized rubber soles are extremely soft and liable to distortion, particularly when a 'sble is of the type used in producing a rolled edge; and in the laying of suc hsoles the soft rubber blanket lessens or obviates the frictional pull of the resilient member upon the rolled up margin of the sole.

It is particularly desirable that the mar- 265,653, filed Zliecember 6, 1918. This 1921. Serial No. 468,882.

feature of, the invention comprises means acting through the elastic member to ez'zert such bending up and pressing action. In the illustrative machine there is located beneath the elastic member, which may consist of the cords or blanket,- or both, a form or mold the inner edge of the rim of which has an outline corresponding to, but slightly larger than, the outline of the bottom of the shoe. With this construction, when the shoe is forced against the elastic member and into the mold, this inner edge acts through the elastic member both tobend the margin of the sole upwardly and to press it against the sides of the shoe.

One of the results which must be accomplished in properly laying a rubber sole is with a quantity of small pieoes'of rubber I which may take the formof small rubber balls. When the shoe is forced into the mold in the manner which has been explained above, these rubber balls are both displaced and deformed so that a firm and practically uniform pressure is applied to every. point on the bottom of the sole.

These and other features of the invention,

including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and pointed out in the appended claims. Referring now to the accompanying draw- 1ngs,--

Fig. 1 is a front elevation of the upper portion of a machine in which the present invention is embodied, a lasted shoe being shown as about to be operated upon;

Fig. 2 is a side elevation of the same parts shown in Fig. 1 but with thedasted shoe omitted; U

Fig.3 is a cross-section on an enlarged scale through the sole laylng bed, a lasted shoe with its rubber sole being shown 1n the position which they occupy before the shoe is forced into the mold;

Fi 4 is a view similar to Fig. 3 but showing the shoe forced into the mold;

Fig 5 is a perspective, with certain parts brokenaway, of the sole laying bedv as a whole; 7

Fig. 6 is a detail elevation showing oneshoe and its sole in the sa'merelative position as the shoe and. sole shown in Fig. 3, the sole in Fig. 9, however, being considerably wider and being beveled on its upper margin, and i Y Fig. 10 is a view of the same shoe and sole as are shown in Fig. 9 after the sole has been laid, the edge in this case being a rolled or semi-rolled edge instead of the so-called square edge shown in Fig. 4.

On the drawings a carrier for the solelaying bed is indicated at 10. In the present instance this carrier moves up and-down, its

movement being guided by the irods-ll, 11, and any'suitable mechanism may be employed for moving it up to apply the solelaying pressure, and for drawing it'down after the sole has been laid, the duration of the application of pressure being very short owing to the nature of uncured rubber. A lasted shoe is indicated at 12; and the last. 13 is supported against the sole-laying pressure by a heel-post 14 and a toe-post 15. The heel-post 14 is provided with a'last pin 16, and the last is provided with a socket 17 for the reception of said pin. The toe-post is provided with a toe-rest in the form of a roll 18 composedof suitable soft material such as rubber. The heel-post and the toe post are afiixed adjustably to an, adjustable head 19, the latter being arranged to slide up and down on the guide rods. 11, 11. The head is bored and tapped for the reception of adjusting screws 20, 20, the latter being mounted to rotate in a-station'aryhead 21. These screws aresustained against upward movement by shoulders 22 bearing againstthe under side of head 21, and are sustained against downward movement by the hubs of .bevel gears 23, 23. Bevel gears 24, 24fixed to shaft 25 coact with gears 23, 23 respectively to turn the adjusting screws in unison for the purpose of adjusting the heel-post and toepost up or down. The shaft- 25 is provided "a support for the lasted shoe; and, although in the illustrated machine the lasted shoe is actually carried by this-jack-post structure, it will be understood that the term support as used in the claims is intended to apply to any element or structure which will support 'or back up the lasted shoe against pressure applied to the sole thereof "whether such support is movableor stationary. The heelpost and toe-post are adjustable toward and 'from each other along a ledge formed on the head 19. The shoe-supporting structure, which has been thusbriefiy described, is or may be substantially the same as that shown and described in Patent No. 1,163,589 granted upon an application filed in my name, and

no further description of its details will be t given. The mechanism for causing the carrier 10 to be raised and lowered has not been shown since any suitable mechanism maybe used which will act rapidly so as not to prolong the pressure upon the uncured rubber sole. Preferably toggle mechanism'operated throughv a one-revolution clutch and controlled by a treadle in provided.

The sole-laying'bed comprises a frame 27 and a series of strips or cords 28. These cords are composed of a substance such as what is known in the trade as pure gum rubber, and possess ahigh degree ofelasticity, deformability and flexibility. The frame 27. is formed with an opening, and the cords 28"arearranged to, extend in contiguous relation across said opening so as to form a substantially continuous layer or the usual manner is cover, each cord being anchored at both ends to the frame, the anchorage' being effected in the present instance by hitch pins 30 projecting laterally from opposite sides of the frame. .Althoughthe .cords are referred to as separate-and distinct elements they may be formed if desired by one or more relativelylong strips of rubber or other sub- .llO

stance having the qualities hereinbefore ascribed 'to them. The integral character of the cords in such case is true only in a structural sense, whereas in function the cords. are independent of each other. Fig. 5

shows the entire series of cords, as comprismg three dist nct strips or lengths ofelastlc material, but a'single strip of suflicient length would serve the purpose as well, or if desired the cords maybe separate one from another and separatelyfa'sten'ed to the.

ends of each run with the result that the tension applied to one cord will not be transmitted to an adjacent cord. It r61:

lows, therefore, that each cord Will sustain the sole-laying pressure applied to it without transmitting the stress to the neighboring cords and without depending upon the neighboring cords to assist it.

To the sides of the frame are hinged cov- .ers or guards 33, the longitudinal curvature of the upper edges or faces of which conform generally, as will be seen from Fig. 1, to the longitudinal curvature of the bottom of the lasted shoe. The frame 27 is removably held in place on the carrier 10 by dowel pins 35.

Located in the opening in the frame 27 is a container or box in the form of a mold 37,

the inner edge 137 of the rim of which has an outline corresponding to, but slightly larger than the outline of the bottom of the shoe; The longitudinal contour of'the top of the rim, like that of the top of the guards 33, corresponds to the longitudinal curvature of the bottom of the shoe. The mold L may be in one piece, if desired, in which case a series of interchangeable molds are usedto take care of dilterent sizes of shoes;

but in' the present case an' adjustable mold is shown, said mold comprising two sections slidable toward and from each other on rods orpins, one'o'f which is shown at 39.

In order 'to .adjust the parts of the mold, a rod '41exten'ds through one part and has at each enda hand wheel and a pinion, one of the latter of which is shown at 43. The pinions mesh respectively with racks, one pair of which is shown at 47, 49, one member of each pair being fastened-to one part of the mold and the other member to the other part so that rotation of the rod 45 in one direction separates the parts of the mold and inthe other direction moves them toward each other. For a purpose presently to be explained, the two parts of the mold are provided at both ends with registering slots 51 in which are located plates 53so that the ends of the mold are always closed whatever the adjustment I of the parts thereof.

"With the construction thus far described, the operation of the machine is as follows: A. lasted shoe with the sole 100 placed on the bottom thereof is mounted upon the jack-posts in the position shown in Fig. 1 and power is applied to the machine. The eii'ect of this is to cause the whole sole-laying bed to rise and thereby to force the lower portion of the shoe against the series at rubber cords 28. The first part of this Emotion applies pressure to the bottom of the sole and thereafter the edge or margin of the sole is bent upwardly and pressed against the lower sides of the shoe, it being I understood that thedistanc'e from the edge 137 of the mold to thesides of the shoe is somewhat less than the thickness of the cords. In Figs. 3 and 4,\the illustrative sole is a comparatively narrow one and is bev-. eled on its lower margin so that at the completion of the operation the sole has substantially a square edge with respect to the bottom. The sole 200, which is illustrated in Figs. 9 and 10, is relatively wider and is beveled on its uppermargin so that at the completion of the operation a greater extent of the margin'has been bent upwardly and pressed against the side of the shoe. It will be understood, of course, that unvulcanized rubber is very sticky and that as soon as a sole has been pressed firmly into contact with the shoe it will remain in place. It

should alsobeunderstood that the operation of the machine is a'very rapid one, the duration of the application "of pressure being 7 about one second.

.In order to increase the pressure upon the bottom of the sole, the mold 37 may be partly'or wholly filled with a plurality of loose, freely shiftable, pieces of material, herein shown as a quantityof small'rubber balls 63 which normally fill or practically 'fill the cavity in the mold, as illustrated in Fig. 3. When the shoe is forced into the mold in the manner illustrated in Fig. 4, these rubber balls are more or less displaced and deformed with the result that a firm and substantially uniform pressure is exerted upon the bottom of the sole. The functionof the plates 51,,which prevent the escape of the balls from the mold, will now be clear. The bottom of the'mold is also maintained closed as will be clear from the construction shown in Figs. 3 and 4.

In order to supplement the action of the elastic cords'or, if desired, to take the place of the cords when the rubber balls or similar pieces are usedyone or more rubber blankets 65 may be laid upon the cords or upon the rim of the mold. In Figs. 3 and 4, a blanket 65 rests upon the cords 28, the moldbeing practically filled with rubber balls. In short, all of these elements may be used at the same time; and preferab y they are so used, although as has been explained. certain of them may be dispensed with. As has been explained, the uncured rubber of which rubber soles are made or which they contain in large quantity is very sticky; The rubber blanket referred to above is preferably made of pure gum so as to give it the required elasticity and deformability; and it has been found that the roles tend to adhere to the blanket. in order'to prevent such adhesion the surface of the'blanket may be treated with sulphur chloride or in any suitable manner so as to produce a coat or skin of rubber which is vulcanized to a greater degree than is the body of the blanket. This hardened skin is so thin as not to affect appreciably the-flexibility and elasticity of the blanket, and at the same time reduces the tendency to sticking to the sole. Referring now to Figs. 7 and 8, the effect of the rim 137 on the mold will'be pointed out more particularly. F ig, 7 is a crosssection on the vertical portion of the line 77 of Fig. .3 and shows the blanket and the cords 28 in their normal condition. Fig. 8 is a cross section on the line 88 of Fig. 4 and shows that theblanket 65 and the cords 28 at this locality have been considerably deformed and are exerting pressure against the side of the shoe. The outline of the inner edge 1.37 of the mold. as has been explained, corre-- sponds to but is somewhat larger than the outline of the bottom of the shoe, the distance from the edge to the sides of the Shoe being somewhat less than the thickness'ot the elastic member Whether said member consists of cords, of blankets or of both. When the shoe is forced into the mold, this edge efiects pressure through the elastic member toward the lower portion of the sides of the shoe and thereby bends the margin of the sole upwardly and presses it firmly into place. The purpose of making the illustrative mold in two parts which are adjustable is to permit varying the distance from the inner edge 137 of the mold to the sides of the shoe so as to be able to control the pressure against the sides ofthe shoe and to provide for shoes of difierent sizes. lhe same result can, of coursegbe obtained either with the illustrative mold or with a one-piece mold by using blankets of difierent thicknesses or byproviding a plurality of blankets and using, the desired number with any given shoe.

Although the invention has been described as embodied in a machine for laying unvulcanized rubber soles, it should be understood thatthe invention is not limited in the scope of its application to the particular machine which has been shown and described.
